Lubrication is the "blood" of equipment. If you choose the wrong oil or use the wrong method, the equipment may be "sub-healthy" at best, or even scrapped at worst! This lubrication standard manual used by the industry can help you avoid 90% of lubrication pitfalls!
1. Lubrication standards: national standard/international standard comparison Pollution control: ISO 4406 and NAS 1638 standards, quantify the particle pollution level, and must be inspected for precision equipment! Viscosity index: GB/T 1995 standard, high temperature becomes thinner and low temperature becomes thicker? Choose high viscosity index oil (such as VI>120)! Moisture content: GB/T 260 test, oil with excessive moisture will emulsify, corrode metals, and accelerate equipment aging. Flash point and pour point: GB/T 3536 (flash point), GB/T 3535 (pour point), afraid of ignition at high temperature and solidification at low temperature? Look at these two items!
2. Lubricant selection: 5 key factors
3. Lubrication cycle: The more often the better! New equipment: The oil must be changed after the first 200 hours of operation (such as reducer). Regular cycle: Continuous work (>10h/day): Oil change every 3 months Intermittent work: Oil change every 6 months Abnormal signal: Black oil color, increased foam, viscosity change → Check immediately!
4. Lubrication method: From "manual" to "intelligent" 1. Manual oiling: Oil gun/oil cup, suitable for low speed and light load (such as chain). 2. Splash lubrication: Gears rotate with oil, pay attention to the oil level not being too high (1-2 teeth high in oil). 3. Centralized lubrication: Electric pump + distributor, precise control of oil volume (such as injection molding machine guide rail). Intelligent lubrication: 4. Sensor monitoring: Real-time feedback of bearing temperature and oil pressure
5. Pit avoidance guide: 90% of people have stepped on these mines! Misunderstanding 1: "The more lubricating oil, the better" → Excessive amount leads to poor heat dissipation and 15% increase in energy consumption. Myth 2: “It’s OK to mix different oils” → Chemical reaction of additives, performance drops sharply!
Correct approach: Clean the oil nozzle before refueling to prevent contamination. Record the oil change time and brand to avoid mixing. Recycle and dispose of waste oil to avoid environmental penalties.
Lubrication is not “refueling”, but scientific management throughout the entire life cycle of the equipment!
